C Correct answer
Explanation

First train travels for 4 hours (4pm to 8pm) at 80 kmph, covering 320 km. Second train starts at 8pm at 120 kmph. Relative speed = 120 - 80 = 40 kmph. Time to catch up = 320/40 = 8 hours. Distance from A = 120 × 8 = 960 km. The second train overtakes the first at 960 km from station A.
